To all 'whom t may concern.' Be it Alrnown that we, AUGUST F. BEITZELLand BERNARD D. vVV-nmnnnA citizens of the United States, residingat'Baltimore, in the county of Baltimore City and State of Maryland,have invented new and useful Improvements in Power-Transmission.ll/leans, of which the following is a specication.

This invention relates to improvements 1n transmission means for powerplants and the principal object'of the invention is to provide means fordriving the driven element at a greater speed than the driving element.

Another object of the invention ls'to provide a casing for containingthe gearing and shafts of the transmission means with means whereby thesame may be easily connected with the driving and driven elementswithout opening the casing.

The invention also consists in certain other features of the severalparts7 to be hereinafter fully described, illustrated in theaccompanying drawings and specifically pointed out in the appendedclaim. t

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in Which v Figure1 is an elevation of a power plant connected with a propeller andshowing our invention in use.

Figure 2 is a plan View of the invention ralone and with the top of thecasing removed.

Figure 3 is a sectional detail view.

In Figure 1 the power plant is shown at'A and consists of any type ofmotorand lts transmission and controlling means. The propeller is shownat B. 'Our improved speed increasing means is shown at C and connectsthe drive shaft of the engine with the shaft of the propeller so thatsaid propeller shaft is driven at a greater speed than the engine shaft.Y

It will of course be understood that Figure 1 simply shows oneapplication of the invention as the invention may be connected by anyother type of power plant and driven element. f y

The invention comprises a casing 1 which is made suiliciently tight tohold lubricant. It is provided with suitable means for holding it inposition against movement. Centrally located in the .casing is a pair ofmam specification-.of Letterman. '.natnteanebfafiese.- Y

Walls ofthe vcasing Wherefthe shafts'pass through. AThe outer ends oftheshafts 2 and 3 project from the sides ofthe casing and flanges 6 aresecured to their extremities. These flanges are adapted to be bolted tolikeVK vflanges carried by the driving shaft and the driven shaft. Theshafts 2v and 3 are supp orted by anti-friction bearings in the up-`rights 7 located in the casing'and extending from end to end thereof.

The shaft 2 carriesa large gear wheel 8 within the 'casing and the shaft3 carries a lsmall gear-'wheel 9. The gear wheel 8 meshes l greaterspeed than the shaft 2 so thatlthe propeller or other driven elementwill be rotated at-a greater speed. than the enginer shaft. The shafts11 are also providedwith roller bearings 13 where they' pass through theuprights '7 The casing is adaptedftobe illedrwith .lubricant and thenthe top thereof placed inA position thus the friction' o-f the rotatingparts is reduced to a minimum. l

. It will be seen Vthat the device "maybe connected Vwith the drivingand driven elements Without opening the casing as it isfs'implynecessary to bolt the casing in Vposition and connect the flanges (pwiththey driving and, driven shafts. v Y l Y Ifthe apparatus should becomeinoperative for any reason it maybe easily removed and the driven shaft'connected directly with the driving shaft. Y

' lBy using the pair of shafts 11 arranged as shown .the torque andstrain" on the shafts 2 and 3 are reduced to a minimum.

It is thought from .the foregoing descrip-` tion that the advantages andnovel features of 4our invention will be readily apparent.

' We desire it to be understood that'we may4 l parts, provided that suchchanges fall within the scope of the appended claim.

What We claim is:

An apparatus of the character described comprising a casing adapted tohold the lubricant, a pair of main shafts centrally locatedl in saidcasing and arrangedto align together, a roller bearing sleeve adapted tohold the inner ends of said shafts,` roller bearings placed in the Wallsof the casing Where the shafts pass through, and having their outer endsprojecting from the sides of the casing, flanges provided on the outerextreinities of said shafts, uprights located Within the casing andextending from end to end thereof, gears located Within said casing andconnecting the shafts together, said shafts and gears supported by saiduprights, and means for connecting the outer ends of the shafts to thedriven and driving elements. Y

In testimony whereof We aiix our signatures. A
